Abstract

It has been shown that motion can be characterized in the spatiotemporal-frequency (Fourier) domain, and that this phenomenon can be exploited for the computation of optical flow. However in practical (natural) sequences, the signatures of the different motions cannot be resolved in the Fourier domain, nor associated with their respective regions in the image sequence. In this paper we consider the application of a spatiotemporal/spatiotemporal frequency representation (a 3-D version of the widely used Gabor transform) to the computation of optical flow in natural scenes
